502 is caddy cant find lldap, docker wise is it on same docker network? As the config directly

lldap:17170

i assume the caddy on different docker networkt with lldap

They are on the same default network. Pretty sure there's nothing wrong with Caddy or docker compose since I set up Grafana with that same exact entry (with

grafana:3000

) instead and that worked.

This is my minimal sample compose, i can connect with caddy fine

version: "3"
services:
  lldap:
    image: nitnelave/lldap:latest
    ports:
      - 25000:3890
    volumes:
      - data:/app/data
    environment:
      - LLDAP_JWT_SECRET=RANDOMTHINGSTOADD
      - LLDAP_LDAP_USER_PASS=admindemo
      - LLDAP_LDAP_BASE_DN=dc=example,dc=com
      - LLDAP_VERBOSE=true

  caddy:
    image: caddy
    ports:
      - 25100:80
    volumes:
      - ./caddyfile:/etc/caddy/Caddyfile

volumes:
  data:

Caddyfile

# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.

:80 {
    # Set this path to your site's directory.
    root * /usr/share/caddy

    # Enable the static file server.
    file_server

    # Another common task is to set up a reverse proxy:
    reverse_proxy lldap:17170

    # Or serve a PHP site through php-fpm:
    # php_fastcgi localhost:9000
}

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile
# https://github.com/caddyserver/dist/blob/master/config/Caddyfile

yeah i'm not sure why it's unable to connect to lldap when it can connect to grafana just fine. but thanks for your help anyways

maybe just podman acting up for no reason, docker also sometimes just do weird things

I'm inside a shell inside the caddy container, I can verify that it can connect to grafana but not lldap:

sh
/srv # wget --spider -o /dev/stdout grafana:3000
Connecting to grafana:3000 (10.89.0.10:3000)
Connecting to grafana.localhost:50443 ([::1]:50443)
wget: can't connect to remote host: Connection refused
/srv # wget --spider -o /dev/stdout lldap:3000
wget: bad address 'lldap:3000'

it like lldap isolated or so, how about lldap to caddy? podman inspect may show details about the container, the network part

caddy container:

json
               "Networks": {
                    "server_default": {
                         "EndpointID": "",
                         "Gateway": "10.89.0.1",

                         "DriverOpts": null,
                         "IPAMConfig": null,
                         "Links": null,
                         "Aliases": [
                              "caddy",
                              "82b2138689e2"
                         ]
                    }
               }

i think it create another one outside the default, but well it working 🤣

i finally got my usecase working. I set the database url to

postgresql://lldap:${POSTGRESQL_PASSWORD_LLDAP}@%2Fvar%2Frun%2Fpostgresql/lldap

and add

/run/postgresql:/var/run/postgresql

as a volume. now I don't need network access to the host

oh, socket bind connection 👍
